HL-G3 Generator Monitor
The HL-G3 tells you — in real time — whether your generator is actually running, how hard it's working, and how much fuel it has left. Onboard current and vibration sensing detect true run state (not just a key position), and a hardened remote kill relay lets operators shut a runaway or unattended unit down from the dashboard.
